Hello,This is now the third Nucleo board that has been "bricked" by a forced ST-Link V2-1 update. I can no longer program the board. Windows 10/11 sees the board as a USB thumb drive (this has always worked) but from within the STM32CubeIDE it will n...

Hello,I am wondering how to configure the MPU in CubeMX (6.12.1) so that I can enable the D-Cache and the I-Cache. I know the instructions that enable the caches (SCB_Enable_x_Cache(); replace _x_ with I or D) but was wondering on the configuration C...

I am using an STM32H747I-Discovery board for prototyping.I was wondering if I can set:HAL_PWREx_ConfigSupply(PWR_SMPS_1V8_SUPPLIES_LDO); or HAL_PWREx_ConfigSupply(PWR_SMPS_2V5_SUPPLIES_LDO);Then set:__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTA...

Hello,I am using the STM32H747I-DISCO board for prototyping. I was able to load up the "Tutti Frutti" game demo on the board to verify the hardware. In my own application I was able to store a small 320 x 240 image in the internal flash of the STM32H...

I do not know if this will solve the issue for anyone else, but I was able to recover my Nucleo boards.On another computer with the latest versions of STM32CubeIDE and STM32CubeProgrammer I was able to reprogram the Nucleo boards I was having an issu...

Hi @TDK,Thank you for the additional information. I had enabled the MPU but did not understand the setting in CubeMX. I did not make any changes in CubeMX for the MPU (except enable it) when it generated the code. The "MPU_InitStruct.SubRegionDisable...

Tank you everyone for your help.I was able to get it working with the SMPS powering the LDO and running the system clock at 480 MHz.AScha.3, I am accepting you last reply as the solution. I only had to remove the SB46 as C52 and SB19 were already on ...

OK, so what I understand is that I can use the internal SMPS to power the LDO so that I get smooth (low ripple) power to the core (smps -> ldo -> core) and then can run the core at 480 MHz. I just need to make the jumper (solder bridge) changes on th...

Sorry but I might not be understanding correctly.In CubeMX, selecting the STM32H747XIH6 device I can setup the internal SMPS to power the LDO (either set to 1V8 or 2V5) but then it only allows me to set VOS0, VOS1 through 3 are grayed out and not sel...
